A concentrated firming serum for sagging, lined skin
SkinCeuticals A.G.E. Interrupter Ultra Serum is a concentrated anti-ageing serum for mature skin that is losing firmness and definition. It combines a high 34.6% concentration of Flavo-Proxylane with cassia alata extract to target the visible effects of collagen decline and glycation, the process that stiffens and yellows the skin over time. Rhamnose and gentian root extract help maximize the lifting result, so the forehead, cheeks, jawline and neck look tighter and more sculpted.
The texture
A light, fluid serum that spreads easily over face and neck and sinks in without stickiness. It leaves a smooth, silky finish that layers well under moisturizer and sunscreen.
Who it suits
- Mature skin with sagging on the jawline and neck
- Wrinkles and loss of firmness
- Skin that looks dull or sallow with age
- Anyone already using a vitamin C serum in the morning
Worth knowing before you buy: the formula contains fragrance. It is a firming serum, not an exfoliant or retinoid, so pair it with sunscreen every morning to protect the results.
How long one bottle lasts
Used twice a day on face and neck, the 30ml bottle lasts around six to eight weeks.
